INTERNAL-COlYIBUSTION MOTOR.

Application filed June 2,

To all whom. it may concern:

Be it known that I. Vioron l/V. Prion, a citizen of the United States, and a resident of the city of New York, Kew Gardens, borough of Queens, in the county of Queens and State of New York, have invented a new and Improved Internal-Combustion Motor, of which the following is a full, clear, and exact description.

The present invention relates to new and useful improvements in internal combustion motors, and it pertains more particularly to the specific construction of certain parts thereof.

It is one of the primary objects of the invention to so construct a motor that the cam shaft housing thereof will be supported above the cylinders and out of contact there with.

It is a further object of the invention to provide means for supporting the cam shaft directly from the crank case of the motor.

It is a still further object of the invention to utilize the same means which secures the cam shaft in position to secure the main bearings of the crank shaft, thus providing a dual function for the cam shaft housing supporting and fastening means.

The foregoing objects of the invent-ion serve to provide a construction whereby the cam shaft is supported out of contact with the cylinder block or head, thus preventing overheating of the cam shaft and the consequent undue consumption of lubricant at this point.

With the above and other objects in view, reference is had to the accompanying drawing, in which the figure is a vertical sectional view of a motor constructed in accordance with the present invention.

Referring to the drawing, the reference character 5 designates the motor cylinder, 6 designates the upper half of the crank case and 7 designates the lower half thereof.

The reference character 8 designates the cam shaft housing and mounted in said cam shaft housing is a cam shaft 9. Brackets or other suitable supports 10 are rigidly carried by the cam shaft housing 8 and mounted for pivotalmovement on the brackets 10 are rocker arms 11 adapted for engagement with the valve stems 12 to operate the valves 13 shown in dotted lines in the drawing. The upper half 6 of the crank case is provided on its outer surface with a plurality of tubular supporting lugs 15, and said tu- 1921. Serial No. 474,427.

bular supporting lugs 15 extend inwardly of the upper portion 6 of the crank case as indicated by the reference character 16. These tubular extensions 16 are connected together by means of a web or the like 17., the intermediate portion of which is curved as at 18 to provide the upper half of a main bearing 19. The lower half 20 of the main bearing 19 is adapted to be secured in position by means of bolts 21 and nuts 22, the bolts 21 extending upwardly through the tubular members 16 and the lugs 15 and project parallel with the cylinder of a point above the tops thereof.

Surrounding each of the bolts 21 and resting upon the lugs 15 are sleeves or tubular columns 25, and these sleeves or tubular columns 25 have their lower ends flared as at 26. The upper ends of the sleeves or tubular columns 25 are flared as at 27, and form a rest or support for the cam shaft housing 8. Secured to the upper end of each of the bolts 21 is a nut 28, and said nuts serve when tightened to retain the cam shaft housing 8 upon the upper ends of the sleeves or tubular columns 25.

By this construction it is apparent that when it is desired to remove the cam shaft housing 8, it is only necessary to remove the several nuts 28 and the entire cam shaft assembly will be readily removable from the several bolts 21. On the other hand, if it is desired to remove the lower half 20 of any of the main bearings 19, it is only necessary to remove the several nuts 22 and the lower half of the main bearings will readily slip from the lower ends of the bolts 21, it being understood, of course, that the lower half 7 of the crank case has been removed.

From the foregoing it is apparent that the present invention provides a new and novel manner of supporting the cam shaft housing out of contact with the several cylinders of a motor, and, at the same time, gain the several advantages derived from the positioning of the cam shaft over the top of the motor cylinders.

I claim:

1. In an internal combustion motor, a

cam shaft housing support comprising a plurality of tubular members, means carried by the crank case of the motor and forming a rest for said tubular members, and fastoning means in the form of bolts passing through said tubular members and through the cam shaft housing whereby the cam shaft housing is, secured to the tubular members and the tubular members tov the c1:ank case of the motor.

2. In combination With an internal combustion motor, a cam shaft housing, meansv for supporting said cam shaft housing,said

supporting means comprising a plurality of tubular members resting upon the crank case of the motor, and securing means in the form of bolts passing through said tubular members to secure them to the motor crank case. a

3. In combina ion ith an interna 0mbustion motor, a cam shaft assembly sup? porting. and securing means, said. camshaft assembly supp rti g and se u g means comprising a pluralityof lugs formed on the crank case of the motor, tubular members supportedrupon said lugs and engaging the bottom face of the cam shaft housing, abolt passing through each of said tubular members and through a portion of the cam shaft housing, said bolt serving to secure the cam shaft housing to the tubular meme bersand the tubular members to the crank 25 case of themotor.
